How can I find out what drugs a Medicare drug plan covers?

Each Medicare drug plan has a list of prescription drugs that it covers, called a formulary, or drug list. Plans may cover both generic and brand-name prescription drugs. Most prescription drugs used by people with Medicare will be on a plan's drug list. To find out which drugs a plan covers, contact the plan or visit the plan's website. All Medicare drug plans must make sure that the people in their plan can get medically-necessary drugs to treat their conditions.
